Abstract: La presente invención se relaciona con un proceso para conformar elementos de mampostería en concretos aligerados con perlas de poliestireno expandido y los elementos de mampostería así elaborados. Particularmente, la invención se relaciona con un procedimiento para fabricar elementos de mampostería que comprende esencialmente elaborar una mezcla seca de concreto aligerado con perlas previamente impregnadas de minerales finamente pulverizados sobre la superficie de perlas o esferas de poliestireno, y, paso seguido, llevar a una mezcladora de régimen forzado en combinación con agua. Una vez se ha practicado una mezcla homogénea se lleva a una máquina vibrocompactadora para moldear los elementos de mampostería, determinado el nivel de frecuencia de vibración para después pasar a un patio de fraguado. Los elementos obtenidos mediante este proceso comprenden un pesos sustancialmente menor con amplias características de aislamiento térmico y acústico. El menor peso de la mampostería conlleva a aligerar las cargas estructurales de diseño, haciendo más esbeltas las estructuras y por ende más económicas. De igual forma, con la utilización de bloques de concreto aligerado es posible ampliar los formatos tradicionales, cubriendo mas área con menor peso muerto y menor esfuerzo de mano de obra ya que requiere menor cantidad de hierro estructural.

Abstract: Leaching of solid matter from a sludge uses a tubular reactor which is equipped with a concentric central pipe and a double-action mixer. The mixer is located in the vicinity of the central pipe's lower edge. Leaching solid matter from a sludge with the aid of an oxygen-containing gas uses a tubular reactor. The reactor is equipped with a concentric central pipe (2), and a double-action mixer (5) in the vicinity of central pipe's lower edge (7). With the aid of the mixer, the sludge flows downward in the central pipe, and then turns upward outside the central pipe as the gas is fed at the same time into the sludge and dispersed into small bubbles. The mixer preferably has nearly rectangular straight lower blades which facilitate the dispersion of the gas and the turning of the discharge sludge into the upward flow. It has curved upper blades which facilitate the downward flow of the sludge in the central pipe. It is preferred that the cross-section area remaining between the mixer and the central pipe is adjusted to be less than half (preferably at most one third) of the flow cross-section area in the central pipe and the lower edge of the central pipe is at a height (measured form the reactor bottom) of 0.7-1.3 times that of the reactor diameter, preferably the same as the diameter. The cross-section ratio of the central pipe and its surrounding reactor casing is preferably below 0.1.

A gyroscope for missile guidance is provided with internal pyrotechnical charges 4, 5, 6 for starting rotation of the rotor, the changes being adapted to be ignited by passing an electric current from an external source to an electric ignition device 7 within the rotor, the wires 19, 20 for passing this current extending through an axial bore of one of the rotor pivots so that as the rotor is started the wires 19, 20 are twisted off. The rotor comprises two parts 1, 2 which are screwed together to define a chamber 3 containing the primer charge 6 and two annular charges 7, 8. The part 1 contains two nozzles 8 having tangential discharge outlets. The rotor is mounted in a gimbal 13 in pivots 11, 12 the wires 19, 20 passing through the pivot 12. The gimbal 13 is journalled in a further gimbal 14 which is mounted on shafts 15,17 in the gyro frame 16. The gyro is caged by means of a spring loaded plunger 23 (Fig. 3) moving in a cylinder 24. The plunger 23 holds the gimbal 13 so that the spin axis of the rotor is approximately vertical with the missile in its launching position, so that when released the gyro can be used as a vertical reference for the missile. The plunger 23 is spring urged to release the gimbal 13, but is held down by a rod 25 passing through the cylinder 24. The wires 19, 20 pass through a holder 22 which is urged by a spring 27 to move down into the plane of Fig. 1 to remove the twisted off ends of the wires 19, 20 from the vicinity of the rotor. The holder 22 is held up by a wire 28 passing round the gyro frame 16, and fitted with an eye 30 through which the rod 25 passes. In use before launching the missile the rotor is brought to speed by igniting the charges 4, 5, 6. The rod 25 is attached to a stationary part of the launching equipment so that on launching the missile the gyro is uncaged and the wires 19, 20 removed from the vicinity of the rotor. To prevent the rotor from turning before starting and twisting off the wires 19, 20 prematurely a shift 31 (Fig. 3) is provided in the body part 1 and a thread 34 passed through it and holes 32, 33 in the gimbal 13. This thread is torn off when the rotor starts.

The plate 50 may be heated by hot gases. The drift control means shown comprises a manually-controlled jack 72 extending obliquely between a compactor frame member 112 and a horizontal member 94 coupling the parallel tow arms 40, the members 94, 112 being connected by parallel ball-jointed links 96 and the jack 72 being pivoted at one end to a spring device 128. In a modification, Fig. 10 (not shown), the connecting links 96 are replaced by links which can be shifted by hand wheels (360, 362) to move the compactor angularly when negotiating curves. In a further modification, Fig. 7 (not shown), the tow arms diverge from a single vertical pivot (218) and lateral drift is controlled by a longitudinal jack (222) and spring device (250). The drift control jack is actuated by a manual valve, Fig. 7B (not shown) and hydraulic accumulators acting as springs. The paving machine comprises crawler tracks 18, a hopper 20 having front-loading rollers 22, a distributing screw 26, and draw arms 28 for the screed 24. The compactor plate 50 may be widened by attachment plates and is resiliently mounted below a frame 44 by rubber pads and spring- loaded swinging link dampers 70, 70a which are mutually at right angles. In use the compactor frame 44 can move freely up and down the tow arms 40. For transit, Fig. 3 (not shown), the compactor frame is locked to the arms (40) by extending jacks (74) to rotate latches (80), and is supported clear of the ground by lifting arms (28, 40) and lowering caster wheels (48).
